Default More cam duration?

Hi guys. I need to find 20 or 30hp. Had a tuff time going 10.00 this weekend. It was 90 deg. and humid. Ran 10.03/132. Need to find a little more hp to run my 10.00 index easier in the heat.
I was thinking of a bigger cam. Right now it is a easy lob solid roller 278/282 at .050 lift is .640/.645 with 1.5 rockers. 108 ls installed at 106.
Heads flow 330 at .700. 12-1 comp. 455 stock block. I run mufflers if that matters. car is 3200lbs. Converter stalls at 4900. shift at 6400 and trap at 6800rpm. 60's usually in low 1.37's with a best of 1.35.
I tune it with weight and timing to go 10.00/133. Seems like everyone in my class mph's better than me.

Do you think I should try 1.65 rockers first? Any other ideas to pick up a little hp?

Thanks Mike
